Schaefer Brush 43813 Spiral Tube Brush 9/16 in Stainless

Product Description

The SCHAEFER BRUSH 43813 is a double stem spiral tube brush designed for cleaning the interior of tubes, pipes, and small-bore components. The spiral wire construction keeps stainless steel bristles firmly in place under repeated use, maintaining consistent scrubbing action across the full brush length. At 9/16 inch in diameter and 6 inches overall length, with a 4-inch brush length, this tool fits into confined passages where larger brushes cannot reach. The 12-24 female threaded connection allows secure attachment to compatible extension rods or handles. Stainless steel bristles and brush construction resist corrosion, making this brush suitable for use with water, mild chemicals, and other fluids common in maintenance and service work.

This tube brush is suited for maintenance technicians, HVAC service professionals, plumbers, and industrial cleaning personnel who need a reliable small-bore brush for deburring, descaling, or general interior tube cleaning. Typical applications include heat exchanger tubes, condenser tubes, small-diameter pipe fittings, and similar confined bore surfaces. The double stem and spiral design provides firm bristle support, reducing bristle loss during aggressive scrubbing tasks.

Installation Notes

Thread the brush securely onto a compatible 12-24 extension rod or handle before use. Inspect the connection for tightness before inserting the brush into any tube or bore. When cleaning pressurized or energized systems, ensure the system is fully depressurized and de-energized before inserting any tool. Replace the brush if bristles show significant wear or loss to maintain effective cleaning performance.
